Just before an epileptic has a fit, a "larval explosion" of large surges occurs through his brain, three every second, producing 100 to 300 millionths of a volt each. The wave pattern is large, slow and evenly curved but cut by sharp downward strokes which perhaps reflect convulsions in the brain. During the depths of the epileptic fit, the characteristic long slow curves assume an unbroken S-shape...
...transparent baby eels about 2 in. long, with which harbors and rivers teem in the spring. Before spawning, matured eels fast for months, their ultimate death re sulting from starvation. The small eels that return by the myriad are at least a year old, having developed out of a larval stage which Science long took to be a distinct species of surface-dwelling fish, leptocephali, notable for their complete lack of reproductive organs. The presence of eels in waters blocked from the sea by high falls, and in land-locked ponds and lakes, is readily accounted...
...occurred to Dr. Charles H. T. Townsend, a U. S. entomologist stationed at Itaquaquecetuba, Estado de Sao Paulo, Brazil, during his studies of a muscoid fly called Cephenemyia, the world's fastest aeronaut. Much like a bumblebee in size, color and form, Cephenemyia begins life as a larval parasite in the nasal passages or other head cavities of deer, cattle and other ruminants. To find suitable host animals and catch them and get into their noses and out again, the adult flies must range immense tracts of country at terrific speed. To the human eye, their passing...
...practically free from insect pests in past years and it is only during the last few years that there has been any trouble at all. The first troublesome insect was the elm-leaf beetle. It is a small beetle which feeds on the leaves of the elms, in its larval stage, appearing in such numbers as to strip the trees entirely of their foliage, thereby killing them. The trees in the west part of the Yard were attacked by this pest and considerable damage was done before they were overcome...
...leopard moth, which was first noticed in June 1909 is an imported European pest, and is only injurious in its larval stage. The life of the larva is two years. It makes its way into the tree by boring through the bark where it may make great furrows in the growing layer, thus girding the limbs, or it may burrow deeper into the heart of the tree. Its burrows show that it migrates often, from one part of a branch to another or to a different one altogether...
